| description | PCT No. PCT/HU90/00006 Sec. 371 Date Oct. 19, 1990 Sec. 102(e) Date Oct. 19, 1990 PCT Filed Jan. 17, 1990 PCT Pub. No. WO90/08132 PCT Pub. Date Jul. 26, 1990.The invention relates to a process for the preparation of such isomer mixtures of cypermethrine of the Formula (I) (I) wherein carbon atoms indicated by 1, 3 and alpha stand for a chiral carbon atom and the wavy line indicates cis or trans configuration related to the cyclopropane ring-which contains out of the theoretically possible 8-isomers of cypermethrine at least 95% of 1RtransS and 1StransR (Ib) isomer pair or only a mixture of 1RcisC and 1ScisR (Ia) and the isomer pair (Ib) of the ratio (Ia):(Ib)=55:45-25:75 by asymmetric transformation of second order performed in the presence of an amine base and solvent from a starting cypermethrine isomer mixture which contains next to the isomer pair (Ib) cis and other trans isomers or the isomer pair Ia+Ib at an undesired ratio. |
